How to overcome the target release constraint?

It is our intention to FTP objects between IBM iSeries v6r1 and IBM iSeries v3r2.
But when we create the SAVE FILE in IBM iSeries v6r1, in specifying the target release,
We can at most stepdown to v5r3.
Does anybody know how to overcome this constraint?
We want to stepdown to v3r2.
Thanks

Stepping down to V3R2 from i 6.1 is like trying to step down to Windows 98 from Windows 7. It would be very difficult. Very few objects would make sense to such an older platform.

There is no way to use savefiles for such a transfer. There are no objects that can be saved and restored between the two in that direction.

If any such move is made, it has to be done as text files. Any objects would have be copied in source form and recreated. Of course, any source elements that were not available on the older system would have be removed. Any data would have to be exported to text files also, and then the data would need to be imported after the containers were recompiled.

It's likely that the only way to transfer the text files would be with FTP. There won't be many other networking protocols that could be used. I'm not sure if there would be many ways to communicate with PCs, for example, though it might be possible to use Windows 2000. Better would be Windows 98. Networking protocols from 15 years ago are needed. If you can find ways to make them work, it might be possible.

Compiled objects from i 6.1 cannot be restored to a V3R2 system. Period.

Not only are the objects likely to have many compiler attributes that cannot be processed by such an old release, but at least two different levels of changes to internal structures have happened. It's possible to go backwards through one level of such changes (from version 6 to version 5) if the objects were compiled to allow it. That's part of what the TGTRLS() attribute does. But version 6 of the OS has no information about internal structures used by version 4, much less version 3. Expecting to go back through at least 11 different releases over 4 versions of the OS makes no sense.

And the underlying hardware adds a huge obstacle. A one-way upgrade going forward from CISC to RISC is to be expected. IBM even allowed backwards conversion from RISC back to CISC for a number of OS releases, but that was dropped late in version 4. The RISC systems not only had a radically different machine language, but there was also a change from 48-bit addressing to 64-bits when RISC was first introduced.

For any practical thought, it cannot be done. It'd be cheaper, easier and faster simply to obtain a used system that runs i 6.1.
